TECHNICAL FIELD OF THE INVENTION

The invention relates to the identification of an RNA-binding domain, its mode of binding with a cognate RNA, and methods enabling design and selection of inhibitors of its binding site.

BACKGROUND OF THE INVENTION

With over 36 classes of known anti-ribosomal agents, the bacterial ribosome has been exploited for decades as a target for antibiotic drugs. The essentiality, selectivity, and conserved nature of bacterial translation continue to make the ribosome one of the most attractive targets for the discovery of antibacterial agents. The recent elucidation of the crystal structures of the 30S and 50S ribosomal subunits from Thermus thermophilus (Wimberly et al., (2000) Nature 407, 327-339) and Haloarcula matsumorii (Ban et al., (2000) Science 289, 905-920), respectively have provided an enormous amount of detailed structural information regarding RNA and protein structure, RNA-protein interactions, and ribosome assembly. In addition, these revolutionary discoveries have provided a structural basis for understanding the mechanistic processes of translation and the action of antibiotics, and may also allow for the de novo design of new antibacterial drugs that target the translation machinery.

Ribosomal protein S8 is an excellent target for the discovery of new antibacterials. In addition to being absolutely required for the proper assembly of the 30S ribosomal subunit in E. coli, the invention provide that S8 in S. pneumoniae is essential for bacterial growth. Moreover, alterations in S8-rRNA affinity can be correlated with growth defects that result from the expression of the same mutations in E. coli (Gregory and Zimmermann, (1986), Nucleic Acids Research 14, 5761-76). Ribosomal protein S8 is also a broad-spectrum target, as it is predicted to be very well conserved among bacterial species, see Table 1. Although there is a human ribosomal protein S8, it is significantly divergent and not thought to be a functional homolog of the bacterial S8. In addition, there does not appear to be any helix 21 homology in eukaryotic 18S rRNA.

Ribosomal protein S8 is a primary rRNA-binding protein that binds directly to a central region of bacterial 16S rRNA called Helix 21. Since S8 is required for the co-operative binding of all 30S proteins, it is essential for the proper assembly of the small ribosomal subunit (Held et al., (1974) J. Biol. Chem 249, 3101-3111). Indeed, mutations within the protein have been shown to result in ribosome assembly in defects in E. coli (Geyl et al. (1977) Mol Gen Genet. 29, 331-6). The binding site of S8 within Helix 21 rRNA has been extensively characterised in E. coli, and consists of two helical segments interrupted by a very highly conserved core element of irregular structure that spans nucleotides 595-598 and 640-644 of 16S rRNA. An unusual feature of this core element, which has been elucidated by NMR studies (Kalurachchi et al., (1 997) Proc. Natl Acad. Sci USA 94, 2139-2144), is the existence of a base triple element between nucleotides A595 and the A596/U644 base pair in the E. coli rRNA. The deletion of A595 severely impairs the binding of E. coli S8 (Mougel et al., (1993) Eur J. Biochem. 215, 787-792), indicating that this nucleotide is critical for RNA-protein recognition. Interestingly, this base triple is predicted by comparative phylogenetic evidence to be nearly universally-conserved in prokaryotes (Gutell (1993), Nucleic Acids Res. 21, 3051-3054).

While the S8-RNA interactions have been extensively characterized in E. coli, and the crystal structures of both B. stearothermophilus and T. Thermophilus S8 have been solved, prior to this invention very little was known regarding the structure and RNA-binding activities of ribosomal proteins from a pathogenic bacterial species. This problem is solved by the instant invention that provides cloned, expressed, and purified Staphylococcus aureus ribosomal protein S8, and RNA-binding studies showing a specific interaction between S8 and S. aureus or E. coli helix 21 RNAs. Mutagenesis studies also provided herein have defined nucleotides in the core RNA element from S. aureus that are essential for recognition by S8 and suggest a conservation of the structure of helix 21 in this organism. Also provided herein is a crystal structure of the native S8 protein from S. aureus to 1.56 Å resolution, and superimposition of this structure into the 30S ribosomal subunit structure of T. thermophilus has provided regions of contact with a cognate rRNA. Characterisation of S. aureus S8, taken together with a recent published crystal structure of the 30S ribosomal subunit (Wimberly et al., (2000) Nature 407, 327-339) advances understanding of bacterial ribosome architecture and allows for rational design of broad-spectrum antibiotics that target the translational apparatus.

The instant invention further provides a crystal structure of the protein S8 from the small ribosomal subunit of Staphylococcus aureus in its native state. A preferred structure shows that S8 presents two surfaces that are suited to bind a cognate rRNA. On of them is a α-helix that binds into the major groove of the double stranded rRNA. A second surface is one in which conserved residues are located and are critical for binding to a cognate rRNA. S8 interacts with rRNA through this second surface by an interaction that can be described as “riding” over the double helix. Given the significant role of S8 in organising and binding rRNA for proper ribosomal function and therefore proper protein synthesis, targeting either interaction between S8 and rRNA for disruption with small molecules could result in an effective antimicrobial.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides a S8 from Staphylococcus aureus crystalline structure of the native enzyme.

S8 Protein From Staphylococcus aureus Crystalline Three-dimensional Structure.

Overall Structure

The crystal structures of S8 from Staphylococcus aureus in its native form has been determined and refined to 1.50 Å resolution. The final model includes residues 4-132 and a total of 281 water molecules as in FIG. 1. The polypeptide chain has an α+β fold divided in a somewhat defined two halves of the molecule: two α-helices and three β-strands form the N-terminal half of the molecule, and the C-terminal half is formed by a small helix and three short, anti-parallel strands. The N- and the C-terminus of molecule are located on opposite sides of the S8 molecule and the loop that connects the N- and C-terminal halves of the molecule protrudes into the solvent on the same side of the molecule as the C-terminus and opposite to the largest surface used by S8 to bind the rRNA.

rRNA Binding

Superposition of a S. aureus S8 onto a S8 of the S30 ribosomal subunit of T thermophylus (1FJG) indicates that there are two regions of interaction with the rRNA: the N-terminal helix formed by residues 5-19 inserts into a major groove of a double helix formed by nucleotides A820-A885. The second interacting surface is formed by residues 4-6, 30-32, 56-57, 82-92, 107-111, and 122-125 on the N-terminus side of a molecule that rides on a double helix formed by nucleotides A587-A758. Either of these two contact surfaces could be targets for small molecules that disrupt the interaction; which by affecting S8-rRNA interactions, ribosomal function would be impaired to the extent of being lethal for a bacterum.

Table 2 provides atomic coordinates of native crystal structures of S8 from S. aureus. The amino acid sequence of S8 from S. aureus is provided in SEQ ID No. 1. Small variations in the atomic coordinates shown in Table 2 will occur such as upon refinement of a crystal structure from a different crystal form that will result in a new set of coordinates. The deviation on Cα atoms from the present coordinate set is not expected to substantially exceed a rms of 2.5 Å. Similarly, bond angles and bond lengths will usually vary within a small range.(Engh, R. A., and Huber, R. (1991) Acta Crystallogr. A47, 392-400.), however, the inter-atomic interactions in Table 2 will remain constant, within the experimental error, as will the relative conformation and orientation or positioning of residues in the rRNA-binding site.

Mutants and Derivatives

The invention further provides homologues, co-complexes, mutants and derivatives of the S8 crystal structure of the invention.

The term “homologue” means a protein having at least 30% amino acid sequence identity with a functional domain of S8. Preferably the percentage identity will be 40, or 50%, more preferably 60 or 70% and most preferably 80 or 90%. A 95% identity is most particularly preferred.

The term “co-complex” means the S8 or a mutant or homologue of the S8 in covalent or non-covalent association with a chemical entity or compound.

The term “mutant” refers to the S8 polypeptide, i.e., a polypeptide displaying the biological activity of wild-type S8 activity, characterized by the replacement of at least one active-site amino acid from the wild-type sequence. Such a mutant may be prepared, for example, by expression of the S8 rRNA-binding protein cDNA previously altered in its coding sequence by oligonucleotide-directed mutagenesis.

S8 mutants may also be generated by site-specific incorporation of unnatural amino acids into the S8 protein using the general biosynthetic method of C. J. Noren et al, Science, 244: 182-188 (1989). In this method, the codon encoding the amino acid of interest in wild-type S8 is replaced by a “blank” nonsense codon, TAG, using oligonucleotide-directed mutagenesis. A suppressor directed against this codon is then chemically aminoacylated in vitro with the desired unnatural amino acid. The aminoacylated residue is then added to an in vitro translation system to yield a mutant S8 protein with the site-specific incorporated unnatural amino acid.

Selenocysteine or selenomethionine may be incorporated into wild-type or mutant S8 protein by expression of S8-encoding cDNAs in auxotrophic E. coli strains (W. A. Hendrickson et al, EMBO J., 9 (5): 1665-1672 (1990)) or a normal strain grown in a medium supplemented with appropriate nutrients that will prevent endogenous synthesis of methionine. In either of these methods, the wild-type or mutated undecaprenyl pyrophosphate synthase cDNA may be expressed in a host organism on a growth medium depleted of either natural cysteine or methionine (or both) but enriched in selenocysteine or selenomethionine (or both).

The term “heavy atom derivative” refers to derivatives of S8 produced by chemically modifying a crystal of S8. In practice, a native crystal is treated by immersing it in a solution containing the desired metal salt, or organometallic compound, e.g., lead chloride, gold thiomalate, thimerosal or uranyl acetate, which upon diffusion into the protein crystal can bind to the protein. The location of the bound heavy metal atom site(s) can be determined by X-ray diffraction analysis of the treated crystal. This information, in turn, is used to generate the phase angle information needed to construct a three-dimensional electron density map from that a model of the atomic structure of the enzyme is derived (T. L. Blundel and N. L. Johnson, Protein Crystallography, Academic Press (1976)).

The term “space group” refers to the arrangement of entities (i.e. molecules) throughout the crystal lattice. There are only 132 possible arrangements, each one unique and identified by a symbol. The space group symbol is formed by a letter (P, F, I, C) and numbers with or without subscripts, for example: P2₁, I222, C2₁2₁2₁, etc.

Methods of Identifying Inhibitors of the S8 From Staphylococcus aureus Crystalline Structure

Another aspect of this invention involves a method for identifying inhibitors of S8 protein characterized by the crystal structure described herein, and the inhibitors themselves. The S8 crystal structure of the invention permits the identification of inhibitors of the rRNA-binding activity of a Staphylococcus aureus S8. Such inhibitors may bind to all or a portion of the active site of the S8; or even be competitive, non-competitive, or uncompetitive inhibitors. Once identified and screened for biological activity, these inhibitors may be used therapeutically or prophylactically to block the rRNA-binding activity of a Staphylococcus aureus S8, and thus, inhibit proper assembly of the small ribosomal subunit.

One design approach is to probe the S8 crystal of the invention with molecules composed of a variety of different chemical entities to determine optimal sites for interaction between candidate inhibitors and the rRNA-binding activity of S8. For example, high resolution X-ray diffraction data collected from crystals soaked in or co-crystallized with other molecules allows the determination of where each type of solvent molecule sticks. (J. Travis (1993) Science, 262:1374). Molecules that bind tightly to those sites can then be further modified and synthesized and tested for the ability to inhibit rRNA-binding activity of S8.

The time-dependent analysis of structural changes in S8 protein during its interaction with other molecules is permitted. The reaction intermediates of S8 protein can also be deduced from the reaction product in co-complex with S8 protein. Such information is useful to design improved analogues of S8 protein inhibitors or to design classes of inhibitors based on the reaction intermediates of the S8 protein and binding activity of S8 inhibitor co-complex. This provides a novel route for designing S8 inhibitors with both high specificity and stability.

Another approach made possible by this invention, is to screen computationally small molecule data bases for chemical entities or compounds that can bind in whole, or in part, to the S8 protein. In this screening, the quality of fit of such entities or compounds to the binding site may be judged either by shape complementarity or by estimated interaction energy (E. C. Meng et al, J. Comp. Chem., 13:505-524 (1992)).

Because S8 may crystallize in more than one crystal form, the structure coordinates of S8, or portions thereof, as provided by this invention are particularly useful to solve the structure of those other crystal forms of S8. They may also be used to solve the structure of S8 mutants, S8 co-complexes, or of the crystalline form of any other protein with significant amino acid sequence homology to any functional domain of S8.

One method that may be employed for this purpose is molecular replacement. In this method, the unknown crystal structure, whether it is another crystal form of S8, an S8 mutant, or an S8 co-complex, or the crystal of some other protein with significant amino acid sequence homology to any functional domain of S8, may be determined using the S8 structure coordinates of this invention as provided in Table 2. This method will provide an accurate structural form for the unknown crystal more quickly and efficiently than attempting to determine such information ab initio.

Thus, the S8 structure provided herein permits the screening of molecules and/or the designing of new molecules that bind to the S8 protein structure, particularly at the active site, via the use of computerized evaluation systems. For example, computer modelling systems are available in that the sequence of the S8, and the S8 structure (i.e., atomic coordinates of S8 and/or the atomic coordinate of the active site cavity, bond angles, dihedral angles, distances between atoms in the active site region, etc. as provided by Table 2 herein) may be input. Thus, a machine readable medium may be encoded with data representing the coordinates of Table 2. The computer then generates structural details of the site into that a test compound should bind, thereby enabling the determination of the complementary structural details of said test compound.

More particularly, the design of compounds that bind to or inhibit S8 according to this invention generally involves consideration of two factors. First, the compound must be capable of physically and structurally associating with the S8 protein. Non-covalent molecular interactions important in the association of S8 protein with its ligands include hydrogen bonding, van der Waals and hydrophobic interactions.

Second, the compound must be able to assume a conformation that allows it to associate with S8 protein. Although certain portions of the compound will not directly participate in this association of an S8 protein, those portions may still influence the overall conformation of the molecule. This, in turn, may have a significant impact on potency. Such conformational requirements include the overall three-dimensional structure and orientation of the chemical entity or compound in relation to all or a portion of the binding site, e.g., active site or accessory binding site of S8 protein, or the spacing between functional groups of a compound comprising several chemical entities that directly interact with S8, such as rRNA.

The potential inhibitory or binding effect of a chemical compound on S8 may be analyzed prior to its actual synthesis and testing by the use of computer modelling techniques. If the theoretical structure of the given compound suggests insufficient interaction and association between it and S8, synthesis and testing of the compound is obviated. However, if computer modelling indicates a strong interaction, the molecule may then be synthesized and tested for its ability to bind to S8 and inhibit using a suitable assay. In this manner, synthesis of inoperative compounds may be avoided.

An inhibitory or other binding compound of S8 may be computationally evaluated and designed by means of a series of steps in that chemical entities or fragments are screened and selected for their ability to associate with the individual binding pockets or other areas of S8 protein.

One skilled in the art may use one of several methods to screen chemical entities or fragments for their ability to associate with S8 and more particularly with the individual binding pockets of the S8 active site or accessory binding site. This process may begin by visual inspection of, for example, the active site on the computer screen based on the S8 coordinates in Table 2. Selected fragments or chemical entities may then be positioned in a variety of orientations, or docked, within a binding pocket of S8. Docking may be accomplished using software such as Quanta and Sybyl, followed by energy minimization and molecular dynamics with standard molecular mechanics forcefields, such as CHARMM and AMBER.

Specialized computer programs may also assist in the process of selecting fragments or chemical entities. These include:

Additional commercially available computer databases for small molecular compounds includes Cambridge Structural Database, Fine Chemical Database, and CONCORD, for a review see Rusinko, A., Chem. Des. Auto. News 8, 44-47 (1993).

Once suitable chemical entities or fragments have been selected, they can be assembled into a single compound or inhibitor. Assembly may be proceed by visual inspection of the relationship of the fragments to each other on the three-dimensional image displayed on a computer screen in relation to the structure coordinates of S8 protein. This would be followed by manual model building using software such as Quanta or Sybyl.

Useful programs to aid one of skill in the art in connecting the individual chemical entities or fragments include:

Instead of proceeding to build an S8 protein inhibitor in a step-wise fashion one fragment or chemical entity at a time as described above, inhibitory or other S8 binding compounds may be designed as a whole or “de novo” using either an empty active site or optionally including some portion(s) of a known ligand(s). These methods include:

Chem., 33:883-894 (1990). See also, M. A. Navia and M. A. Murcko, “The Use of Structural Information in Drug Design”, Current Opinions in Structural Biology, 2:202-210 (1992). For example, where the structures of test compounds are known, a model of the test compound may be superimposed over the model of the structure of the invention. Numerous methods and techniques are known in the art for performing this step, any of which may be used. See, e.g., P. S. Farmer, Drug Design, Ariens, E. J., ed., Vol. 10, pp 119-143 (Academic Press, New York, 1980); U.S. Pat. No. 5,331,573; U.S. Pat. No. 5,500,807; C. Verlinde, Structure, 2:577-587 (1994); and I. D. Kuntz, Science, 257:1078-1082 (1992). The model building techniques and computer evaluation systems described herein are not a limitation on the present invention.

Thus, using these computer evaluation systems, a large number of compounds may be quickly and easily examined and expensive and lengthy biochemical testing avoided. Moreover, the need for actual synthesis of many compounds is effectively eliminated.

In another aspect, the S8 structure of the invention permit the design and identification of synthetic compounds and/or other molecules that have a shape complimentary to the conformation of the S8 active site of the invention. Using known computer systems, the coordinates of the S8 structure of the invention may be provided in machine readable form, the test compounds designed and/or screened and their conformations superimposed on the structure of the invention. Subsequently, suitable candidates identified as above may be screened for the desired S8 inhibitory bioactivity, stability, and the like.

Once identified and screened for biological activity, these inhibitors may be used therapeutically or prophylactically to block rRNA-binding activity of S8, and thus, inhibit proper assembly of the small ribosomal subunit.

As used herein the term “natural product molecule” includes all non-synthetic products of nature and includes, but is not limited to, derivatives, extracts or homologs thereof, having, or containing, a bioactive component.

Another aspect of this invention involves a method for identifying inhibitors of a S8 characterized by the crystal structure and rRNA-binding site described herein. The S8 from S. aureus crystalline structure of the invention permits the identification of inhibitors of ribosomal function. Such inhibitors may be competitive, binding to all or a portion of the rRNA-binding site of the S8; or non-competitive and bind to and inhibit ribosomal assembly or function whether or not it is bound to another chemical entity.

One design approach is to probe the S8 crystal of the invention with molecules composed of a variety of different chemical entities to determine optimal sites for interaction between candidate S8 inhibitors and the protein. For example, high resolution X-ray diffraction data collected from crystals saturated with solvent allows the determination of where each type of solvent molecule binds. Small molecules that bind tightly to those sites can then be designed and synthesized and tested for their S8 inhibitor activity.

This invention also enables the development of compounds that can isomerize to short-lived reaction intermediates in the chemical reaction of a substrate or other compound that binds to or with the S8. Thus, the time-dependent analysis of structural changes in the S8 during its interaction with other molecules is permitted. The reaction intermediates of the S8 can also be deduced from the reaction product in co-complex with the S8. Such information is useful to design improved analogues of known S8 inhibitors or to design classes of inhibitors based on the reaction intermediates of the S8-rRNA and S8 inhibitor co-complex. This provides a route for designing S8 inhibitors with both high specificity and stability.

Another approach made possible by this invention is to screen computationally small molecule databases for chemical entities or compounds that can bind in whole, or in part, to the S8 protein. Details on this process and the results it can provide are now documented in the art. For a description of this type of technology please refer to PCT application WO 97/16177 published 09 May 1997; the techniques described there for computer modeling are incorporated herein by reference.

Once identified by the modeling techniques, the inhibitor of ribosomal function may be tested for bio-activity using standard techniques. For example, the structure of the invention may be used in activity assays to determine the inhibitory activity of the compounds or binding assays using conventional formats to screen inhibitors. One particularly suitable assay format includes the enzyme-linked immunosorbent assay (ELISA). Other assay formats may be used; these assay formats are not a limitation on the present invention.

In another aspect, the S8 structure of the invention permit the design and identification of synthetic compounds and/or other molecules that are characterized by the conformation of the S8 of the invention. Using known computer systems, the coordinates of the S8 structure of the invention may be provided in machine readable form, the test compounds designed and/or screened and their conformations superimposed on the structure of the S8 of the invention. Subsequently, suitable candidates identified as above may be screened for the desired inhibitory bio-activity, stability, and the like.

Once identified and screened for biological activity, these inhibitors may be used therapeutically or prophylactically to block S8 function, and thus, overcome bacterial resistance to antibiotics, for example, of the beta-lactam class, eg. imipenem, penicillins, cephalosporins, etc. by using an entirely different mechanism of attacking bacteria in diseases produced by bacterial infection.

The following examples illustrate various aspects of this invention. These examples do not limit the scope of this invention that is defined by the appended claims.

EXAMPLE 1 The Expression and Purification of the S8 From Staphylococcus aureus in Escherichia coli

The gene for S. aureus S8 was PCR amplified from strain WCUH29 genomic DNA, and the resulting fragment was cloned into pET28a(+) for expression in E. coli. The S. aureus S8-expression construct (S8sa-pET28) was transformed into BL21(DE3) cells for expression and purified by cation exchange chromatography. The soluble polypeptide includes 132 amino acid residues with a molecular weight of 14,830 Da. This product was greater than 95% pure by SDS PAGE, has the desired RNA-binding activity, and N-terminal amino acid analysis confirmed its identity. A one liter culture of E. coli haboring the S8 expression construct was induced with IPTG for three hours at 37° C. FIG. 2 shows that very little of the overexpressed protein was present in the soluble fraction (lane 5). After solubilization of the protein in 6M urea and purification by anion exchange chromatography, the resulting protein appeared to be greater than 95% pure. N-terminal sequencing, MALDI-MS and AA analysis all confirmed the identity of the purified protein.

1.A. Measurement of S8 Activity.

It is also possible to define ligand interactions with S8 in experiments that are not dependent upon enzyme catalyzed turnover of substrates. This type of experiment can be done in a number of ways:

1.B.1. Effects of Ligand Binding Upon Intrinsic Fluorescence (e.g. of Tryptophan).

Binding of either natural ligands or inhibitors may result in the protein's conformational changes that alter its fluorescence. Using stopped-flow fluorescence equipment, this can be used to define the microscopic rate constants that describe binding. Alternatively, steady-state fluorescence titration methods can yield the overall dissociation constant for binding in the same way that these are accessed through enzyme inhibition experiments.

EXAMPLE 2 Crystallization, Structure Determination and Refinement of the Crystal Structure of the S8 from S. aureus

2.A. Crystallization

Single crystals of native S8 grew from sitting drops prepared by mixing 2 μL protein with 2 μL of reservoir solution containing 30% PEG4000, 0.2M Li₂SO₄, 0.1M Tis-HCl, pH 8.5. The drops were left to equilibrate at room temperature against 500 μL of the reservoir solution. By registering the position and intensity of many tens of thousands of diffraction spots using the computer program HKL2000 (Otwinowski, Z. and Minor, W. (1996) Methods in Enzymology 276, 307-326) and, program MOSFLM (A. G. W. Leslie, MRC Laboratory of Molecular Biology, Hills Road, Cambridge, UK and Collaborative Computational Project, Number 4, (1994) Acta Cryst. D50, 760-763.) the crystal has been determined to be the orthorhombic space group P2₁2₁2₁ and have unit cell parameters (lattice constants): a=42.1 Å, b=55.9 Å, c=61.3 Å, alpha=beta=gamma=90.0° and one molecule in the asymmetric unit.

2.B. X-ray Diffraction Data Collection

The crystal was picked up with a loop and frozen by quickly submerging it into liquid nitrogen before mounting it under the cold stream. Diffraction data was collected at CHESS F2 beamline using 1.000 Å wavelength x-rays and the ADSC QuantumIV detector. The data was integrated, reduced and scaled with DPS/MOSFLM/SCALA (CCP4). The data collection statistics are shown in Table 3.

2.C. Structure Determination

The structure was determined by molecular replacement using the program AmoRe (Navaza). and the atomic coordinates of the S8 structure from B. stearothermophylus (1SEI). The solution had a correlation coefficient of 0.50 and R=0.49. The correct amino acid sequence was traced before refinement. The suite of programs CNX was used for the refinement and the interactive graphics program O was used for manipulating the model. The final model includes residue 4 to 132 and 281 water molecules. Residues 1 to 3 are not visible in the electron density map.

2.D. Model Building and Refinement

The electron density map was of high quality and afforded the placement of the complete molecule using the interactive computer graphics program O (Jones, T. A. et al. (1991) Acta Crystallogr. A47: 110-119). The model was refined against diffraction data by successive rounds of simulated annealing with torsion angle dynamics, positional refinement and restrained B-factor refinement using CNX (A. Brunger et al., Science, 235: 458-460 (1987)) followed by manual intervention. The refinement and manual rebuilding was monitored by the quality of the 2Fo-Fc and Fo-Fc electron density maps and the value of the crystallographic R and R_(free). The final R is 0.19 and the R_(free) is 0.23 for 23,473 reflections to 1.50 Å resolution. The rms deviation from the reference bond lengths and bond angles (Engh & Huber (1991) Acta Crystallogr. A47: 392-400) are 0.017 Å and 1.8°, respectively. The refined model includes residues 4-132 according to the amino acid sequence SEQ ID NO:1. The N-terminal residues 1 to 3 were disordered in the four molecules. In the refined model, all the main chain conformations fall in the “allowed” regions of the Ramachandran plot. The refinement statistics are shown in Table 4.

EXAMPLE 3 Identifying Inhibitors of Activity of the S. aureus S8 Protein

Avi-tagged S8 was expressed in E. coli along with with BirA (biotin ligase), and LC/MS indicated that approximately 50% of the S8 contained the biotin group at the N-terminus (data not shown). RNA filter-binding studies established that the biotinylated Avi-tagged S8 protein recognized Helix 21 rRNA with an affinity comparable to the untagged protein, Table 5, indicating that the peptide tag and subsequent labeling have no adverse effect on RNA-protein recognition. This biotinylated protein was then used to develop a high throughput-screening assay, which will be used to detect inhibitors of the S8-rRNA interaction. The basis of the scintillation proximity assay is shown in FIG. 5. Essentially, the Helix 21 rRNA fragment is labeled with ³³P or ³H (either internally or at the -3′ or 5′-ends), and a complex is allowed to form with the biotinylated S8 protein. After formation of the RNA-protein complex, streptavidin SPA beads (Amersham Pharmacia) are added and incubated with the RNA-protein complex, and the samples are read in a microplate scintillation counter (eg, TopCount by Packard). Using biotinylated (Avi-tagged) S. aureus ribosomal protein S8, ³³P-labeled helix 21 RNA, and streptavidin SPA beads, a specific signal due to protein-RNA binding was detected, FIG. 6( a). When Helix 21 ΔA649 substrate was used in the SPA assay, no signal above background could be detected, indicating the validity of the SPA format as a viable assay to examine S8-rRNA interactions, FIG. 6( b). The specificity of S8-rRNA recognition was further validated in the SPA format by titrating the binding reactions with unlabeled cognate and non-cognate RNAs. Results show that the addition of excess, unlabeled, wild-type Helix 21 RNA competes the SPA signal to near background levels, while the addition of like amounts of Helix 21 ΔA649 RNA does not (data not shown). This further indicates that the SPA format reflects true recognition of 16S rRNA by S8 protein. This assay can be transferred to a multi-well format (example, 96- or 384-well microplates) for high throughput screening of diverse compound collections. Such compounds that inhibit the S8-rRNA interaction may be useful anti-bacterials.

3.A. Cloning of S. aureus S8

The gene for S. aureus S8 was PCR amplified from strain WCUH29 genomic DNA using a forward primer containing a BspHI site (5′-ACTTC CTCATGACAATGACAGATCCAATCG-3′) (SEQ ID NO: 3) and a reverse primer containing a HindIII site (5′-CTTCTCAAGCTTTTACCAAACGTATGCGATAA-3′) (SEQ ID NO: 4). The 419bp fragment was digested with BspHI and HindIII, purified, and ligated into pET28a(+) cut with NcoI and HindIII. Positive transformants were confirmed by sequencing.

3.B. pET24-AviTag Vector Construction

A linker was made encoding the AviTag (Avidity, see below) with an NdeI 5′ overhang, 3′ BamHI overhang and containing a unique ScaI site after the tag. This was ligated into pET24b(+) from Novagen cut with NdeI and BamHI.

Cloning of AviTag-S8 Construct

The intact S. aureus S8 gene was PCR amplified from WCUH29 genomic DNA using Pwo polymerase (Roche) and the following primers: forward (5′-ATGACAATGACAGATCCAATCGC-3′) (SEQ ID NO: 8) and reverse (5′-TTTACCAAACGTATGCGATAATTTC-3′) (SEQ ID NO: 9). The 400 bp fragment was kinased and ligated into pET24-AviTag digested with ScaI and dephosphorylated. The construct was confirmed by sequencing and transformed into BL21 (DE3) cells containing pACYCbirA (Avidity) for expression of the biotinylated-AviTag-S8.

3.D. Protein Expression and Purification

The S. aureus S8-expression construct (S8sa-pET28) was transformed into BL21(DE3) cells for expression and a 10 ml overnight culture in LB, 50 ug/ml Kanamycin, 1% glucose was diluted 1:100 and grown to an OD₆₀₀ of 0.55. IPTG was added to 0.5 mM and induction carried out for 3 h at 37° C. Cells were lysed in 30ml (5 ml/g wet weight) of 50 mM Na-phosphate pH 7.5 and lysed via sonication and freeze/thaw. After centrifugation, the pellet was solubilized in 30 ml of 6M Urea/20 mM Tris pH 7.0 (Buffer A) and the filtered supernatant applied to a 5 ml HiTrap SP column. S8 was eluted with a 40 column volume gradient of 0-1M NaCl in Buffer A. Fractions containing S8 were pooled and refolded by dialysis against several changes of 80 mM Hepes pH 7.6 and 1M KCl. Aliquots were frozen in a dry ice/ethanol bath and stored at −80° C. Integrity of the protein was confirmed by N-terminal sequencing, MALDI-MS and AA analysis. Yield from the 1 liter culture was 36 mg of purified protein.

3.E. Expression and Purification of B-Avi-S8

5 ml of an overnight LB/Kanamycin (50 ug/ml)/Chloramphenicol (34 ug/ml)/1% glucose culture was diluted 100-fold into media containing 50 uM biotin. The culture was grown at 37° C./250 rpm to an OD₆₀₀ of 0.5, IPTG was added to 0.5 mM and growth continued at 37° C. for an additional 3 h. Pelleted cells were homogenized in 6M Urea/20 mM Tris pH7.0 (BufferA) in a volume of 5 ml/g cells. Clarified lysate was applied to a 5 ml HiTrapSP column (Amersham Pharmacia) and eluted with a 40 column volume gradient of 0-1M NaCl in BufferA. Fractions containing B-Avi-S8 were pooled and dialized at 4° C. against 80 mM Hepes pH 7.6/1M KCl. Aliquots were quick-frozen and stored at −80° C. N-terminal sequencing, LC/MS and AA analysis confirm the integrity of the protein. Yield was 14 mg of greater than 90% purity from a 500 ml culture with ˜50% biotinylation.

3.F. Cloning and Transcription of Helix 21 rRNAs

A DNA fragment corresponding to Helix 21 (nts 584-655) of E. coli 16S rRNA was amplified by PCR of E. coli genomic DNA. A T7-promoter sequence was incorporated into the fragment by the 5′-primer, and the fragment was cloned into the EcoRI-KpnI sites of pUC19 to generate pUC-EcH21. Helix 21 from Staphylococcus aureus (corresponding to nts 596-659 of 16S rRNA) was cloned downstream of a T7 promoter in a similar manner to generate the plasmid pUC-SaH21. The generation of mutant derivatives of S. aureus Helix 21 was done by incorporation of site directed mutagenesis of PCR primers. Unlabeled RNAs were trancribed from BamHI-linearized DNA templates using MEGAshortscript kit (Ambion Inc., Austin, Tex.). RNA substrates for filter-binding studies were made by end-labeling with γ-³²P or ³³P-ATP.

3.G. Filter-binding

For filter-binding experiments, labeled RNAs were renatured by preincubation in binding buffer (80 mM HEPES-KOH pH 7.6, 350 mM KOAc, 20 mM MgOAc) for fifteen minutes at 40° C. Renatured RNA was then mixed with the appropriate amount of protein and then incubated for fifteen minutes on ice and then filtered immediately on 0.45 μM nitrocellulose filters (Whatman), washed with 1.0 ml of binding buffer, and then counted in a scintillation counter. K_(d)'s were determined from several independent binding experiments for each substrate RNA.

3.H. Characterisation of the RNA-binding Activity of S. aureus S8

In order to characterise the RNA-binding activity of S. aureus S8, an RNA-filter-binding assay was developed. The results of these experiments, shown in FIG. 3, demonstrate that the interaction of S8 with wild-type Helix 21 RNA has a measured affinity of approximately 400 nM. This interaction is highly specific, in that an RNA containing a deletion of A603 fails to demonstrate any appreciable binding by S8. This result also highlights the importance of the base triple within helix 21, as A603 is predicted to interact with the A604-U652 basepair.

Several mutations were introduced into Helix 21 rRNA, shown in FIG. 4, and the apparent dissociation constants for the interaction of S8 and these variant RNA substrates was examined. These results are shown in Table 5. Substitution of the A-U base pair (nts 604-652) with G-C result in a tenfold decrease in binding affinity. This nucleotide substitution is predicted to maintain the stem structure in this region but it changes the primary sequence of the RNA. Since S8 still binds to this RNA, albeit at a tenfold decreased affinity, this underscores the fact that while maintenance of the secondary structure in this region is required, the exact sequence of the RNA is necessary for optimal recognition by S8. Deletion of A649, and substitutions of C651-U and A650C651-U all result in the complete abrogation of binding by S8, suggesting the critical importance of nucleotides in this region. The conserved nature of this RNA-protein recognition is further demonstrated by the fact that S. aureus S8 can recognize E. coli Helix 21 rRNA with a similar affinity as with S. aureus Helix 21 rRNA.

EXAMPLE 4 Modeling Studies of S. aureus S8-rRNA Binding

Superposition of the S. aureus S8 onto the S8 in the S30 ribosomal subunit of T thermophilus (1FJG), shown in FIG. 12( a), indicates that there are two regions of interaction with the rRNA: residues 5-19 (N-terminal α-helix) with nucleotides A820-A885 and residues 4-6, 30-32, 56-57, 82-92, 107-111, and 122-125 with nucleotides A587-A758. This second RNA-interacting face is in direct contact with bases and more likely the surface to target with inhibitors that disrupt the S8-rRNA interaction(s).

The surface representation of S. aureus S8 protein is shown in FIG. 14( a). The N-terminus, marked with less dense stippling (20%), is the region predicted to bind to rRNA in T. thermophylus S30 ribosomal particle and presumably also in S. aureus where it rides on the rRNA formed by a double stranded stem structure formed by nucleotides A587 to A758 in 1FJG. In FIG. 14( b), the calculated surface electrostatic potential shows that the S8-rRNA interactions are not predominantly electrostatic. In this interacting surfaces there appears to be cavities between protein and the rRNA that may accommodate drug(s) that could interfere with the normal S8-rRNA interaction.

FIG. 13 shows a model of T. thermophilus helix 21 rRNA binding to the “underside” of S. aureus S8. S8 residues S107, T108, S109, and E126 make contacts with helix 21 nts A642, C643, and G644 (the highly-conserved base triple). This modeling data is consistent with the biochemical data showing that nucleotides in this base triple are critical for accurate recognition by S. aureus S8 as shown in Table 5.

-   1. Under the heading ATOM appears a “atom number” (e.g. 1,2,3,4 . .     . etc) and the “atom name” (e.g. CA, CB, N, . . . etc) such that to     each “atom name” in the coordinate list corresponds an “atom     number”. -   2.
